| Title: |
Unified Color Control Method for Mult-Color Light |
| Abstract: |
A unified color control method for a multi-color light, including the following control steps: S1: setting unified color control system and color implementation system for different light sources; S2: inputting a target color parameter, and calculating a target color chromaticity coordinate (xt,yt) by the color control system according to the target color parameter: S3: calculating a primary-color duty ratio Di of corrected colors by the color implementation system using a linear programming equation according to the target color chromaticity coordinate (xt,yt), and a chromaticity coordinate value (xi,yi) and a maximum brightness value Yi of each primary color for each light source under a maximum duty ratio, in which i represents an i-th primary color; and S4: updating colors by the light sources according to the primary-color duty ratio Di of corrected colors in step S3. |
